Main issues, as the Inspector framed them
- The effect of the proposal on the character and appearance of the surrounding area, including the Trewellard Conservation Area, the Cornwall and West Devon Mining Landscape World Heritage Site and the Cornwall National Landscape as designated heritage assets
What decided it
The proposal would not harm the significance of the Engine House as a non-designated heritage asset or the character and appearance of the conservation area, and therefore accords with the development plan, making the shortfall in housing land supply immaterial to the decision.
Although the Council cannot demonstrate a five-year housing land supply, the presumption in favour of sustainable development is not engaged because the proposal accords with the development plan in relation to the designated heritage assets on and around the site, and therefore the housing supply shortfall does not alter the outcome.
